COMBINED HARVESTER TO HARVEST CEREALS

摘要

A combined harvester for harvesting cereals comprises a reaper with a combing device, an inclined two-tier chamber divided by a perforated surface for sieving the grain threshed while combing the grain with the feed conveyers, a device for additional threshing, a transport board, a cleaner and a device for harvesting grain and non-grain part of the yield. The device for additional threshing is made as several combing drums with rows of elastic fingers fixed with the same pitch between the rows arranged in series at the levels which are different according to height thereof. In doing so the position of the rows of fingers of the adjacent drums is shifted along the axis of the drums for one half of a pitch.
